Bits&Chips published an article on the development of a multibeam SEM at ImPhys: "Medical and biological scientists are eager to create 3D images for their research at nanometer resolution. However, without an efficient technique to make the scan, the process is difficult and painfully slow. To make this research feasible, ImPhys/TU Delft is teaming up with a consortium of enterprises to develop and innovative device: a multibeam scanning electron microscope".

The paper introduces a new rigorous method to solve electromagnetic scattering problems in the strong scattering regime. Conventional methods such as FDTD, FEM or integral equation methods require computing the solution of a very large set of linear equations.

An NWO-LIFT grant has been awarded to a consortium of researchers including Elizabeth Carroll and Jacob Hoogenboom from ImPhys. In the consortium, further comprising UMC Groningen and ImPhys spin-off Delmic BV, novel microscopy techniques will be used to better visualize and understand structural/functional properties in medical biology, and to create tissue atlases.

"My research group is mainly experimental, combining optics and biology, so certainly our work is altered a lot right now. I see students feeling grief that they will not be able to achieve all of their original BEP/MEP goals.

Read about David Maresca, one of the 'Rising Stars' of the Delft Health Initiative. Maresca is setting up his own lab at ImPhys. He will focus on biomolecular ultrasound imaging.

Jos van Rooij, PhD student in the group of Jeroen Kalkman, published a paper on polarization contrast optical diffraction tomography (ODT) in a recent issue of Biomedical Optics Express. The paper builds on earlier work on large scale high sensitivity ODT where a zebrafish larva was imaged in phase contrast.

On March 17th, 2020 Hamidreza Heydarian successfully defended his PhD thesis on "Particle fusion in localization microscopy".

Ten pre-University students (5 VWO) started on March 6th the pre-University on Campus Track: Determining g. In four sessions of 4 hours the students will determine the gravitational constant within 1% of the literature value using a free-fall experiment.

Dr Gunasekar, staff scientist at University of Strathclyde and expert in electron backscatter and electron channeling detection, has received a short-term visit grant from the Scottish Universities Physics Alliance to visit the lab of Jacob Hoogenboom at ImPhys this summer.

Jacob Hoogenboom has received a ZonMW Enabling Technologies grant to collaborate with the University Medical Center in Groningen to optimize biological sample preparation for the novel multi-beam SEM that is currently being developed by a public-private partnership including ImPhys.
